I want to design an experiment to see if drinking coffee makes students score higher on tests. What is the dependent variable in this experiment?

The score from the tests

Explanation:

We are learning about variables used within an experiment

We have two variables here -

Independent Variable

Dependent Variable

The question asks "What is the dependent variable in this experiment?"

First off, what is a dependent variable?

Dependent variable - The result or outcome that is being measured

So, if that is the definition, what part of "I want to design an experiment to see if drinking coffee makes students score higher on tests." is the dependent variable?

Well, clearly the outcome that we are looking out for is the score of the tests. Caffeine is being used to see if it makes students score higher on tests, making the test scores the outcome. Making it the dependent variable.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

glycolysis is a process that fuel your metabolism. it is apart of cellular respiration the process that produce atp.
